For trailering, the Harris Flotebote Sunliner 240 I/O 2006 has the edge at 3 lbs dry weight versus 2 104 lbs for the Harris Flotebote Sunliner 180 2011.

Both the Harris Flotebote Sunliner 180 2011 and Harris Flotebote Sunliner 240 I/O 2006 share an 8 ft. 6 in beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads.

Detailed Evaluation & Buyer Recommendation

Harris Flotebote Sunliner 180 2011 vs Harris Flotebote Sunliner 240 I/O 2006 — Same Brand, Different Boat

The Harris Flotebote Sunliner 180 2011 vs Harris Flotebote Sunliner 240 I/O 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Harris Flotebote Sunliner 240 I/O 2006 measures 24,0 feet overall (2006), giving it roughly 6,0 additional feet of deck space compared to the Harris Flotebote Sunliner 180 2011 at 18,0 feet (2011). Weight tells a clearer story for trailering families: the Harris Flotebote Sunliner 180 2011 tips the scales at 2 104 lbs — 2 101 lbs more than the Harris Flotebote Sunliner 240 I/O 2006 at 3 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The Harris Flotebote Sunliner 240 I/O 2006 tops out at 135 hp. Engine specs for the Harris Flotebote Sunliner 180 2011 aren't listed — confirm with a dealer before selecting an outboard.

For family outings this is probably the sharpest distinction between the two. The Harris Flotebote Sunliner 180 2011 is rated for 9 passengers, while the Harris Flotebote Sunliner 240 I/O 2006 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Harris Flotebote Sunliner 180 2011 could be the deciding factor.

Bottom line: Choose the Harris Flotebote Sunliner 180 2011 if your priority is putting more people on the water — it handles 9 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Harris Flotebote Sunliner 240 I/O 2006 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
